Objectives: Studies investigating associations between chronic obstructive pulmonary disease (COPD) outcomes and psychiatric comorbidity have yielded mixed findings. We examined a national sample of hospitalized COPD patients to evaluate the impact of three psychiatric conditions on mortality and readmission. Methods: Department of Veterans Affairs (VA) administrative and laboratory data were used to identify; 26,591 consecutive patients admitted for COPD during October 2006 to September 2008. Associations between psychiatric comorbidity and both 30-day mortality and readmission were examined using generalized estimating equations and Cox proportional hazards regression, respectively, with adjustments for patient demographics, medical comorbidities, illness severity, and clustering within hospitals. Results: Unadjusted 30-day mortality was higher in patients with anxiety (5.3% vs. 3.8% [P < 0.001]) and depression (6.2% vs. 3.8% [
